WILLIAM B. JARVIS, or GRAND nerrns, "MICHIGAN;

RADIATOR oAr.

Application filed July so, 1926. Serial no. 125,919.

The main objects of this invention are;

.First, ..to provide. an improved radiator capwhich' is well adapted to carry or serve i in the claims.

A structure embodyingthe features of the invention is clearly illustrated in the accom panying drawing forming a part of this application, in which:

1 is a vertical section of a structure embodying the features of my invention, the ornamental projecting parts being partially broken away and the shank of a supported ornament, motometer or the like being indicated by dotted lines.

Fig. 2 is a top perspective view.

Fig. 3is a perspective view of the internal parts in disassembled relation.

Referring to the drawing. 1 represents the threaded neck of an automobile radiator. In the embodiment illustrated the cap 2 is internally chambered and provided with internal threads to engage the neck.

The cap illustrated is provided with ornamental projections partially shown at 3, the shank of a top ornament or the like being indicated by dotted lines at 4. These, however, form no part of my invention but are illustrated in order to bring out some of the advantages of the structure.

The cap has a central bore 5 through the top to receive the shank of a supported part, this bore being closed when the cap is finished without any top ornament and adapted toreceive'such by means of a closure disk 6 which may be punched out to receive the stem of the ornament or supported part.

Depending within the cap is an annular flange-like support 7 having an internal shoulder 8 engaged by the lip or flange 9 on the closure plate 10. This closure-plate has a bore corresponding to that of the cap and registers therewith, the'lip being in the. form I of a flange aroundthe hole in the plate.

I The cap also has a downwardlyfacing. annular groove 11 which is adapted toreceiveth-e blade or tongue-like springs 12 struck up from the annular thrustmember 13,1 these tongues being arranged in the groove iito'position the thrust member lat-- erally and alsoprevent such colla psi ngiof the springs'as would destroy their useful ness'or set them. The dimensions of the thrust member. are such tliatit engages the cap at the edge of the groove...

A resilient gasket 14 is arranged between the closure plate and the end of the neck of'theradiator as shown in 1. 'This' combination of thrust member, closure plate and gasket yieldingly supports the gasket so as to prevent injury to the same as the cap,

is screwed down and also serving as a friction means for holding the cap in its adjusted positions with its. projecting parts properly located relative to the radiator, 1

Further, a seal is provided so that water or steam does not pass above the gasket and down at the outside thereof between the threads. A verypertectseallis provided, and as stated the gasketis protected so that it is not distorted or injured by the cap being screweddown toofan;

I have illustrated and a e-and an em. bodiment of my improvementswhich I have found very satisfactory. I, have not attempted to illustrate or describe other embodiments or adaptations which I contemplate as I believe this disclosure will enable those skilled inthe art to. embody or adapt my improvements as desired.

Having thus described my invention what.

I claim as new and desire to secure byLetters Patent is:

'1. .The combination with a threaded neck, 7' of a chambered cap having a central bore in thetop thereof with a downwardly projectmg internally shouldered flange at its lower end, said. cap having an internal annular groove therein, a gasket arranged to engage the end of the neck, anannular thrust member for applying yielding pressure to said gasket and for retainingthe capin adjusted'positionson said neck. said thrust mem} her having a plurality of spring members struckup therefrom, the outer ends of said spring members being disposed in said annular groove, the thrust member being of i such size as to engage the cap at the side of the} groovewhen. the springs are fully compressed, and a closure member disposed with its outer edge between said thrust memher and gasket and providedwith a bore registering with the bore of said cap andwith an upturned flange-like lip about its bore engaged in the recess formed by the shoulder in sa1d cap-flange. I

p The combination-with athreaded neck, of a chambered cap havinga centralborem the top thereof with a downwardly projecting flange at itslower end, said cap having an internal'annular groove therein, a gasket arranged toengage, the end of the neck, an

7 annular thrust member for applying yielding pressure to said gasket and for retaining the capfin adjusted positions onsaidneck,

said thrust member. having a plurality of blade spring members, disposed in said ana nular groove, and. a closure member disposed withits outer edge between said thrust member and gasket and. engaged with said cap flange. a v 7 Y 3. The combination with a threaded neck,

- of a chambered internally threaded cap hav ing'an internal downwardly projectin sup port member and an internal. annular groove in the top, a thrust member provided with springs engaged in said groove, a gasket disposed to engage the. end of theneck, and a closure plate mounted on SitlCl support with its outeredge disposed between said gasket of a chambered caphaving a depending support, a closure plate'engaging with saidsup port whereby it is held in a central position, a thrust member disposed above said closure plate, and a gasket disposed between said closure plate and the end of the neck, said thrusti nember constituting means for applying yielding pressure to the'gasket and retaining the cap'in its adjustedpositions on the neck.

6. The combination with a threaded neck,

' of a chambered internally threaded caphaving an internal annular groove-in the top, an annular thrust member prov ded with integral springs engaged in said groove, and

a gasket disposed below urged against said thrust member. V H v 7. The combination with a threaded neck, of achambered internally threadedcap having an internal annular groove in thetop v thereet, a thrust member provided with a plurality ofintegral springs disposed with their outer ends in said groove, and afgasket disposed to engage the end of the neck, said ing yielding pressure to the gasket and retaining'the cap in its adjusted position on the neck. r r v 8. The combination with a'threaded neck,

thrustmember' constituting means for, applyof chambered cap having a downw ardly facing internal groove and adownwardly projectingv internal closure plate support member, a closure plate, a'gasket arranged between the end of the neck and said closure plate, and an annular thrust-member acting onsaid closure plate for applying yielding 'pressure 'to said gasket-and retaining the cap in adjusted positions onfsaid;

neck, said thrust member having a plurality of spring members engaged in said groove. I have hereunto set In witness whereof my hand.
